Bifacial Mono PERC Double Glass Module

Product Overview

The bifacial mono PERC double glass module is a cutting-edge photovoltaic solution designed for maximum energy yield and long-term reliability in demanding environments. Leveraging advanced monocrystalline PERC (Passivated Emitter and Rear Cell) technology, this module captures sunlight from both front and rear surfaces, significantly boosting overall performance compared to traditional monofacial panels. Encapsulated between two layers of high-transparency tempered glass, it offers unparalleled resistance to environmental stressors such as PID (Potential Induced Degradation), microcracks, and extreme weather conditions.

Ideal for utility-scale solar farms, commercial installations, and innovative applications like agrivoltaics or floating solar systems, the bifacial mono PERC double glass module delivers power outputs ranging from 550W to 580W per panel. Its bifacial design allows albedo reflection from ground surfaces—such as white gravel, snow, or vegetation—to generate up to 30% additional energy, making it a superior choice for optimizing land use and ROI in international solar projects. Manufactured with half-cut cell technology and multi-busbar (MBB) configuration, this module ensures minimal shading losses and superior low-light performance, even under diffuse irradiation.

With a focus on sustainability, each bifacial mono PERC double glass module undergoes rigorous testing to meet international standards like IEC 61215 and IEC 61730, ensuring bankability for EPC contractors and investors worldwide. Whether you're scaling up ground-mounted arrays or retrofitting rooftops, this module provides a robust foundation for your renewable energy portfolio.

Application Scenarios

The bifacial mono PERC double glass module excels in a wide array of deployment scenarios, making it versatile for global solar projects. In utility-scale ground-mounted power plants, its bifacial capability maximizes energy harvest by utilizing reflected light from light-colored soils or reflective covers, ideal for desert or agricultural regions with high albedo. For commercial and industrial rooftops, the double glass design withstands heavy snow accumulation and hail impacts, ensuring uninterrupted operation in urban settings.

Floating solar photovoltaic (FPV) systems benefit from the module's corrosion-resistant construction and enhanced rear-side generation from water reflections, boosting efficiency by 10-15% over standard panels. Agrivoltaic installations—combining solar energy with crop cultivation—leverage the elevated mounting height to allow bifacial light capture while shading crops below. Additionally, this module is perfect for snow-prone areas, where rear-side melting from absorbed heat prevents snow buildup, and for tracking systems that optimize dual-sided exposure throughout the day.

Off-grid applications, such as remote mining operations or telecommunications towers, appreciate its low degradation rate and high specific yield. With proven performance in high-humidity coastal environments and extreme temperature swings, the bifacial mono PERC double glass module supports diverse international trade projects, from Europe's renewable mandates to Asia's massive solar parks.

Advantages

Choosing a bifacial mono PERC double glass module offers distinct advantages over conventional silicon modules. Firstly, the bifacial architecture delivers 10-30% higher energy yields, directly translating to shorter payback periods and improved LCOE (Levelized Cost of Electricity). The double glass encapsulation eliminates yellowing and delamination risks associated with polymer backsheets, providing mechanical robustness that resists ammonia, salt mist, and UV exposure—critical for agrivoltaics near livestock or marine installations.

With a first-year degradation rate under 1% and annual linear degradation of just 0.4%, it guarantees sustained performance over decades, backed by bankable warranties. The frameless or slim-frame design reduces BOS (Balance of System) costs by enabling closer packing densities and lighter mounting structures. Superior temperature coefficients minimize output losses in hot climates, while half-cut cells and MBB technology lower the impact of hotspots and string mismatches.

Environmentally, the recyclable glass construction aligns with circular economy principles, and its high efficiency reduces land footprint for large-scale deployments. Independent tests confirm lower BOS costs by up to 5% due to fewer modules needed per MW. In summary, the bifacial mono PERC double glass module sets a new benchmark for durability, yield, and total lifecycle value in the competitive solar market.
